① Minimal flow resistance (virtually zero);
② Reliable for corrosive media and low-boiling-point liquids due to non-jamming during operation (without lubricant);
③ Achieves complete sealing over a wide pressure and temperature range;
④ Enables rapid opening and closing, with some designs achieving times of only 0.05~0.1s, ensuring compatibility with automated testing systems. Operation is shock-free during rapid opening and closing.
⑤ The spherical closing element automatically positions itself at the boundary;
⑥ Reliable sealing of the working medium on both sides;
⑦ In both fully open and fully closed states, the sealing surfaces of the ball and seat are isolated from the medium, preventing erosion of the sealing surfaces by high-speed media passing through the valve;
⑧ Compact structure and lightweight, making it arguably the most suitable valve structure for cryogenic media systems;
⑨ Symmetrical valve body, especially welded valve body structures, effectively withstands stress from the pipeline;
⑩ The closing element can withstand high pressure differentials during closure. 11. Ball valves with fully welded valve bodies can be buried directly underground, preventing corrosion of the valve internals and extending their service life to up to 30 years. They are the ideal valves for oil and gas pipelines.
